Changes in v5: - Increase CONSOLE_LOGLEVEL to 5 as a hack to get the board booting again - Patch 05/12 "gpio: sifive: Use generic reg read function" has been superseded by commit 2548493ab4. - Rebase onto u-boot/master
Changes in v4: - Add sandbox dt-binding headers to MAINTAINERS - Add test for led behavior - Add test/dm/pinmux.c to patch - Move sandbox_* variables into a priv structure. This resets them to the default state every time we re-probe. - Reformat documentation in dm/pinctrl.h
Changes in v3: - Add dt-bindings/pinctrl/sandbox-pinmux.h to patch
Changes in v2: - Add test for pinmuxing - Don't clear existing pinctrl settings on probe - Re-order GPIOs to match the defaults more closely - Rebase onto v13 of "riscv: Add Sipeed Maix support" - Rewrite FPIOA driver to use pinmux property - Support muxing the output enable signal for each function in the FPIOA - Support output and input inversion in the pinmux driver - Support pinmux property in pinctrl-generic
Sean Anderson (11): pinctrl: Add pinmux property support to pinctrl-generic pinctrl: Reformat documentation in dm/pinctrl.h test: pinmux: Add test for pin muxing pinctrl: Add support for Kendryte K210 FPIOA gpio: dw: Fix warnings about casting int to pointer gpio: dw: Add a trailing underscore to generated name gpio: dw: Return output value when direction is out led: gpio: Default to using node name if label is absent test: dm: Test for default led naming riscv: Add pinmux and gpio bindings for Kendryte K210 riscv: Add FPIOA and GPIO support for Kendryte K210
